4.1.6. Radiator fan

Check

Electric food to the fan of cooling moves via the lock of ignition and the fuse. The control of the fan is made by the thermal sensor installed on the right side in a radiator.

The fan has to turn on at excess of working temperature of the engine, that is several minutes prior to an entrance of an arrow of the index of temperature of the engine to the red sector. If the fan does not turn on, remove wires from the thermal sensor, connect them among themselves and include ignition. If the fan starts working after that probably the thermal sensor which is subject to replacement failed. In case the fan still does not work, check whether tension to the thermal sensor moves. If tension on the thermal sensor is absent, damage of wires is possible, or the fuse fused. If tension moves, check reliability of connection with the mass of the second wire of the sensor. If the thermal sensor and an electrical wiring in good shape, so it is possible, the fan electric motor is damaged. The electric motor can be checked by giving of tension for it additional wires from the accumulator.

Removal
